OK, this is interesting. Apparently it only happens if no data is sent/received over the line for some time.
I had incorrectly configured the DSL Encapsulation mode and didn't get any responses from the remote side due to that. With the correct DSL Encapsulation mode the remote side does respond, and the transmit queue timeout doesn't happen anymore.
